Proposals for curbing gun violence announced Wednesday by President Barack Obama:

NEEDS CONGRESSIONAL ACTION:

- Requiring background checks on all gun sales. The Brady Campaign to Prevent Gun Violence says 40 percent of gun sales are conducted with no criminal background check, such as at gun shows and by private sellers over the Internet or through classified ads. Obama said there should be exceptions for cases like certain transfers among family members and temporary transfers for hunting purposes.

- Reinstating the assault weapons ban. A 10-year ban on high-grade, military-style weapons expired in 2004. Senate Majority Leader Harry Reid, D-Nev., says such a ban might clear the Senate but doubts it could get through the House.
